I looked at motorcraft . com and looked up the 1998 Grand Marquis and it shows :
Coolant Temperature Sensor Connector
Motorcraft part number ( WPT 431 )
Leads : 2 - brown - male
To change the coolant temperature sensor on your 1998 Grand Marquis, first, ensure the engine is cool and disconnect the negative battery terminal. Locate the sensor, which is typically found near the thermostat housing on the engine block. Remove the electrical connector, then unscrew the old sensor using a socket wrench. Install the new sensor, reconnect the electrical connector, and restore the battery connection before checking for leaks and ensuring proper operation.

Unplug electric connector. Sensor is in water jacket so you will need to catch coolant after removing sensor. Properly dispose of old coolant. Install new sensor and just make a little snug (with open-end wrench)- do NOT over tighten. Install electric connector and top off coolant.
Disconnect electric connector from sensor. Remove sensor and catch & properly dispose of coolant that leaks out. Install new sensor and use open end wrench to make snug (DO NOT OVERTIGHTEN). Connect electric connector. Top off coolant. Clear DTC and ensure it does not come back (check engine light).
The coolant level sensor on a 2.4 L is under front of the coolant reservoir towards the engine. It has a 2-wire connector on it.
coolant temperature sensor are located where the coolant runs in the block near the thermostat housing normally the connector are on top of the sensor and the sensor itself screws in with a deep socket. The temperature sensor is usaully located where the coolant runs OUT of the engine close to thermostat housing.
If the low coolant message is on and you are certain that the coolant level is up, then you probably have a faulty sensor or sensor connector. The low coolant indicator should turn itself off as soon as the coolant is filled.
To replace the engine coolant temperature sensor connector in a 2011 Lexus RX 350, first ensure the engine is cool and disconnect the battery. Locate the coolant temperature sensor, usually near the thermostat housing, and carefully unclip the old connector. Then, attach the new connector, ensuring it clicks into place securely. Finally, reconnect the battery and check for proper function.
The coolant sensor is located approx. 1/2 way down the radiator on the passenger side of the vehicle. Disconnect the electrical connector, Remove the spring clip, pull out the sensor, replace with new sensor, replace the spring clip, connect electrical connector.
To replace the coolant sensor on a Honda Rincon, first, ensure the engine is cool and disconnect the battery. Locate the coolant temperature sensor, typically found near the thermostat housing, and unplug the electrical connector. Use a socket to remove the old sensor, then install the new one by tightening it securely and reconnecting the electrical connector. Finally, reconnect the battery and check for leaks after refilling the coolant if necessary.

To install the coolant sensor on a 1998 Volvo S70, first ensure the engine is cool and disconnect the battery. Locate the coolant temperature sensor, typically found near the thermostat housing on the engine block. Remove the electrical connector and unscrew the old sensor using a socket wrench. Install the new sensor by screwing it in place, reconnect the electrical connector, and then reattach the battery. Finally, check for leaks and ensure the coolant level is adequate.
